Declare variables outside of loop - JayAdra - 09-28-2015

Declare your variables outside of the foreach loop.

PHP Code:
$untung 0;
$ongkir 0;

foreach (
$sum->result() as $row) {
  
$untung=$row->jumlah_item;    
}

foreach (
$sumongkir->result() as $row) {
  
$ongkir=($row->total);
}

$total=$untung+$ongkir

Assume two query result in the same size

PHP Code:
// assume $sum->num_rows() == $sumongkir->num_rows()
for ($i 0$i $sum->num_rows(); ++$i) {
    $untung=$sum->row($i)->jumlah_item;
    $ongkir=$sumongkir->row($i)->total;
    $total+=$untung+$ongkir;    


Not sure I understand your question correctly but I think $total may be an array $total[$i]

Maybe I misunderstand something. If you use foreach your way, you only get the last row of the result set. So it something similar to following without the foreach:

PHP Code:
$untung $sum->last_row()->jumlah_item;
$ongkir $sumongkir->last_row()->total;
$total $untung $ongkir
